I know that nexon have created the game or helped to develop it so you can probably go on nexon.com but it is only in Japan and Korea so if you know how to read it and stuff you can go on their nexon website in one of those countries and sign up for Counter Strike Online
You can change your Nexon email but they require a picture ID and signature and parent or guardian signature. http://nxcache.nexon.net/nexon/customer-service/nexon-email-change-instructions.pdf
Sign up at the nexon.net website. Ensure your location/age match the region you are signing up for. Check if the username is taken, and you are over 13.
There is only one way to sine up for Maple. Try checking if you went to the link in the email for Nexon to verify you. It should work then.
on the Nexon website you have to sign in (if you don't have one use your combat arms, it works for nexon) then after you do that there should be a box in the upper left hand corner which shows all of your stuff and nexon points so you click charge nx and choose gift card or wat ever u have. The second way to type in the nexon points code is to sign in on the COMBAT ARMS website and click play now, then after you are at the home page where you start up combat arms on the bottom left hand corner there should be a selection that says charge nx :)
If you are under 13, you cannot sign up for a Nexon Passport. If you are over 13 and it's still rejecting you, check your region. If you are in North America, you should be on the GMS website. If you're in Europe, EMS. There's also KMS and MapleSEA.
Your MapleStory account is your Nexon passport, which you make on http://www.nexon.net/ press the sign up button on the upper right corner of the screen. send a friend request to aravaz on Windia
